Bariatric Revision Surgery in Mexico — Fix Weight Regain, GERD, or a Failed Procedure
If your previous bariatric surgery didn't deliver lasting results, Dr. López's team can help. Sleeve-to-bypass, band conversion, and revision surgery — performed at Accredited hospitals with 2-day inpatient monitoring and staple-line suturing for added safety.
What Is Bariatric Revision Surgery?
Bariatric revision surgery corrects, converts, or refines a previous weight-loss procedure that didn't deliver lasting results — or that caused complications like severe acid reflux. It's a second chance to achieve your goal weight and resolve metabolic issues.
Most revisions are performed laparoscopically. Recovery is similar to a primary procedure, with a 2-day hospital stay and ICU-level nursing throughout. Dr. López uses staple-line suturing for additional safety on every revision.
- Treats weight regain, GERD, slipped band, dilated pouch
- Sleeve, bypass, and band revisions all performed
- Same surgeon performs primary and revision procedures
- Most revisions stay laparoscopic — small incisions
Why Patients Need Revision Surgery
Revision surgery isn't a failure — it's a recognized next step. About 1 in 3 bariatric patients eventually need or benefit from one of these corrections.
Weight Regain
Stomach pouch stretched over time, hunger came back, weight crept up. Conversion to bypass or SADI restores restriction and metabolic effect.
Severe GERD/Reflux
Acid reflux that developed (or worsened) after a gastric sleeve. Sleeve-to-bypass conversion typically resolves it permanently.
Band Complications
Slipped lap-band, erosion, port issues, or simply ineffective weight loss. Removal + sleeve or bypass conversion is the standard fix.
Insufficient Loss
Initial procedure didn't achieve target weight loss. Revising to a stronger procedure (bypass, SADI, duodenal switch) gets results back on track.
Common Revision Procedures We Perform
Each revision is matched to your previous surgery, current weight, and specific goals — discussed in detail during your free consultation.
Sleeve to Roux-en-Y Bypass
Converts a gastric sleeve into a Roux-en-Y bypass. Restores restriction, adds malabsorption, and resolves acid reflux in most patients.
Sleeve to Mini Gastric Bypass
Converts to a single-anastomosis bypass. Simpler than Roux-en-Y, with comparable weight-loss outcomes.
Sleeve to SADI-S / Duodenal Switch
Adds a duodenal-ileal bypass loop (SADI-S) or full duodenal switch to the existing sleeve. Strongest long-term weight loss for high-BMI patients with regain.
Lap-Band Removal + Sleeve / Bypass
Removes a slipped, eroded, or ineffective gastric band and converts to a sleeve (from $5,300) or bypass (from $6,700) in the same procedure.
Bypass Pouch Resizing / Distal Conversion
Resizes a stretched bypass pouch or extends the malabsorptive limb (distal bypass) for additional weight loss.
Bypass Reversal
In rare cases of severe complications (chronic dumping, malnutrition), the bypass can be reversed back to original anatomy.
WEIGHT REGAIN AFTER SLEEVE OR BYPASS
Sleeve Revision for Weight Regain — Not Just Reflux
A common scenario we see: you had a gastric sleeve 3–10 years ago, lost weight at first, but now the pounds are coming back. There is no reflux — just the weight regain. The revision strategy is different, and it depends on the cause.
Weight regain after sleeve gastrectomy affects up to 30% of patients within 5 years, especially when the sleeve was made too large originally or has stretched over time. Bypass after sleeve is one option, but it is not always the best choice.
The 4 Main Causes of Post-Sleeve Weight Regain
Identifying the cause determines the right revision procedure:
- Dilated sleeve (stretched stomach) — the most common cause, 40-50% of regain cases
- Suboptimal hormone response — ghrelin returns or never fully suppressed
- Dietary regression — head hunger and grazing return
- Metabolic adaptation — body fights weight loss, requires more aggressive procedure
Your Revision Options
Decision factors: Current BMI, anatomy on endoscopy, comorbidities, dietary patterns, and your goals. A consultation with Dr. Alejandro López includes upper endoscopy to evaluate sleeve anatomy before recommending the right path.
Is Revision Surgery Right For You?
Revision is a serious decision. Here's how we evaluate whether it's the right next step.
✅Strong Candidate If
- You're at least 12–18 months out from your primary procedure
- Significant weight regain (more than 25% of weight lost)
- Severe acid reflux/GERD that hasn't responded to treatment
- Lap-band complications (slip, erosion, port problems)
- Previous procedure didn't reach target weight loss
- Ready to recommit to dietary and lifestyle changes
⚠️Wait or Reconsider If
- Less than 12 months from primary surgery (still adjusting)
- Active substance abuse or unmanaged eating disorder
- Severe heart, lung, or kidney disease
- Pregnancy, or planning pregnancy in the next 18 months
- Haven't tried diet/exercise changes since the regain started

Patients who got their weight loss back on track — and resolved acid reflux, slipped bands, and stalled progress along the way.
“I had a sleeve 8 years ago and regained 40 lb. Dr. López performed a revision to bypass and resolved my reflux on top of the weight loss. Down 65 lb at 9 months — and my blood sugar levels returned to a healthy range.”

Revision Patient Reviews
“Sleeve regain after 5 years. Dr. López converted me to bypass in Tijuana. Down 60 lb in 8 months and my reflux is completely gone.”
“Lap-band slipped after 7 years. ALO removed it and converted to a sleeve in one operation. Best decision — back to losing weight steadily.”
“Mini bypass revision in Guadalajara. The 2-day hospital stay was reassuring — fully monitored. Recovery was easier than my first surgery.”
“Sleeve to SADI-S in Vallarta. BMI 49 going in, down 90 lb at one year. Dr. López explained everything clearly — no false promises.”
